The family Tetragnathidae is newly separated from the family Araneidae.
Members in this family also build orb webs, but
a little different from Araneidae. They build small to medium size orb webs with open centre while
spiders in family Araneidae build orb webs with dense center. Tetragnathid
are usually horizontally
inclined in sunlit areas.
Species in this family are elongate spiders with long chelicerae and legs.
Unlike the spiders in Araneidae family which first wrap their prey in silk after capture and then bites it,
spiders in family Tetragnathidae bite first and then wrap.
